Another object of my invention is to provide a concrete floor whereinthe reinforcing 15 bars, waste pipes, wiring conduits, etc., may

. be positioned or arranged with a minimum of time and effort and in anexpeditious manner.

Another object of my invention is to provide a simple and economicalmeans for attaining the said objects.

These and other objects are attained by the means described herein anddisclosed by the accompanying drawings, in which:

Serial No. 141,321.

My invention contemplates a temporary flooring or centering 10 supportedby the usual uprights or shoring 11. The temporary flooring beingerected to cover the entire space over which the ceiling and floor areto be constructed. After the shoring has been erected a suitable bondingelement 12 is positioned upon the upper surface 13 of the temporaryflooring 10. The bonding element 12 may be a wire frame of an inverted Ushape and comprises a body portion 14 having arms 15 and 16 extendingtherefrom. The arms 15 and 16 are bent toward one another at the point17 whereby to form an inclined portion 18. The arms 15 and 16 are thenbent upon themselves at 19 to form a base 20 whereby to support thebonding element upon the shoring 10. The free ends 21 of the arms 15 and16 are then bent right angles to the base 20 and extend in a planeparallel to that portion 22 of the arms 15 and 16 secured to the bodyportion 14. This structure provides a way 23 intermediate the free end21 and portion 22 of the arms 15 and 16 having a downwardly and inwardlywedged shape cross section 24.

A series of the bonding elements just described may be joined togetherby suitable bars 25 being secured to the arms 15 and 16, as shown in theleft hand portion of 1. Again, a single bar 26 may be employed, which issecured at 27 to the body portion 14 of the bonding element abovedescribed. The bars 25 and 26 may be secured in any manner to thebonding elements 12 such as by spot welding, soldering or the like, atthe points 27 and 28. By securing the bonding elements 12 together asdescribed above a wire frame results, as disclosed in Fig. 1, that maybe readily positioned in a minimum of time and in an expeditious manner.

After these frames have been positioned a suitable cement-itious orplaster ceiling 29 is poured upon the upper surface 13 of the shoring10, which material enters the way 23 formed intermediate the bentportions of the arms and 16 and surrounds the bonding element from thepoint 17 downwardly, securely embodying the bonding element within thecementitious material as shown in Fig. 1. The cementitious material 30intermediate the bent portions of the arms 15 and 16 forms a key which,after the cementitious material has set, prevents the withdrawal orremoval of the bonding frame from the ceiling after the said ceiling 29has set. After the cementit-ious ceiling 29 has set and hardeneditbecomes the finished ceiling of the room under construction. It shouldbe noted that except for a very narrow strip 31 of the base of thebonding element 12 the entire element is concealed from view.

After the ceiling 29 has set the metal domes or hollow tiles 32 are thenpositioned upon the upper surface 33 of the ceiling 29. The leg 34 ofthe domes 32 is received intermediate the free end 21 and the portion 22of the arms 15 and 16 of the bonding element 12. The free end 21prevents the inward spreading or bending of the leg 34 of the dome 32and the portion 2270f the arm 15 prevents the outward spreading of theleg 34 of the dome 32. After the domes 32 have been positioned, theconcrete floor 35 may be poured, which enters the space 36 intermediateadjacent domes for forming the beam 37. It is readily evident that thebody portion 14 and arms 15 and 16 secured to the body portion 14 of thebonding element 12, as well as the tie rods and 26, are all embedded inthe concrete floor and securely retained in place after the saidconcrete 35 sets and becomes hard. As stated above, the free end 21 ofthe arms 15 and 16 prevents the inward movement of the legs 34 of thedomes 32 which might be caused by the pressure of the concrete bearingagainst the outer surface of the said legs 34. The portion 22 of thearms 15 and 16 secured to the body portion 14 prevents the outwardspread- P mg, as stated above, of the legs 34 due to the pressure of theconcrete upon the upper surface of the domes 32.

In the modified structure illustrated in Fig. 7, the free ends 21 of thearms 15 and 16 have been removed at the upper line of the ceiling 29.This structure may be used where there is no danger of the leg 34 of thedomes 32 bending inwardly, or wherein the pressure on the top of thedome may tend to bend the legs outwardly. The portion 22 of the arms 15and 16 secured to the body portion 14 prevent such a caving or bendingof the dome.

The body portion 14 of the bonding element 12 may have formedintermediate its ends suitable depressions 38 which form a chair for thereinforcing bars 39. The reinforcing bars 39 may be secured to theindividual bonding elements 12 and the tie rods or bars 25 and 26eliminated. In such a structure the reinforcing bars would serve thedouble purpose of securing the frames 12 in spaced rela tion as well asperforming their normal function, namely, that of reinforcing theconcrete.

In Fig. 4 I have illustrated a concrete floor using the bonding elementdisclosed in the right hand portion of Fig. 1 wherein the metal domes 32are secured to the portion 22 of the arms 15 and 16 by means of a tiewire 40. WVith this structure the arms 34 of the metal domes 32 areprecluded from collapsing or bending inward from the pressure of the wetconcrete in the floor and beams. I have also provided reinforcing bars41 embedded within the plastic ceiling 29 whereby to reinforce theceiling 29. It should be noted that when the reinforcing bars 41 areemployed the tie rods or bars 25 and 26 may be eliminated, allowing thebars 41 to serve as a tie means and a reinforcing means.

In Figs. 5 and 6 there is illustrated a channel 42 secured to the arms15 and 16 of the bonding element 12 so positioned as to lie on the uppersurface 33 of the finished ceiling 29. The channels 42 are adapted toreceive the leg 34 of the domes 32 which channel affords continuoussupport for the bonding element and precludes spreading of the legs 34of the dome32. It is readily evident that the structure shown in Fig. 5carries all the necessary means for bondingthe ceiling to the floor,reinforcing the ceiling, reinforcing the beams and floor, and means forinsuring the correct position of the domes during and after the pouringof the concrete to form the beams and floor.

It must be readily evident that I have produced a device wherein afinished ceiling and a concrete floor may be erected in a minimum oftime and with a minimum of labor. After the ceiling 29 has set the uppersurface 33 thereof may be walked upon by the workmen and the like forarranging any waste pipes, reinforcing bars, electric wiring conduits,etc., that it may be desired to place upon such a ceilin It is alsoevident that the surface may be walked upon for positioning the metaldomes 32 and that the danger of injury to the finished surface of theceiling is absolutely eliminated.

What I claim is:

1. A. combined bar support, tile spacer and key device comprising spacedinverted U shape wire frames having arms for supporting the frames, andfor supporting and spacin tiles, and connector members, spacedlysecuring the frames and providing with the frames, elongated structuresfor aligning a plurality of adjoining tiles and for gauging adjacentrows of adjoining tiles.

2. A floor in the course of construction, the combination of temporarcentering, a plurality of rows of frames, ars connecting and securingthe frames of individual rows of frames, the frames comprising keyportions disposed at the bottom of the frames, rows of XVILLIAM M.GOLDSMITH.
